    All:

I'm using this Snort signature to distinguish between the original and recent 
varient of CodeRed.  I'm sure it can be optimized -- grabbed a bit of the 
binary around the text "CodeRedII" in the packet to cut down on false 
alarms.. putting it out so folks can log the differences.


alert tcp any any -> any 80 (msg: "CodeRedII Overflow"; flags: A+; content: 
"|46309a02 0000e80a 00000043 6f646552 65644949 008b1c24
ff55d866 0bc00f95|"; depth:624;)


Best Regards,
Joe Moll
